-route to namsan-
there are some routes for namsan tour; from myongdong, from hoehyun, etc...
but my favorite route is from gwanhwhamun.
from gwangwhamun to namsan library: by bus no. 402
from namsan library to the top of the mountain: on foot.
(singing merry songs such as 歩こう、歩こう! 私はゲンキ! 歩くのダイスキ! or
Help, I need somebody Help, not just anybody Help!)
from top of the mountain to the observatory room: by elevator.
